The length of the rectangular parallelepiped is 20 cm, and the width is 1 dm larger, the height is equal to the sum of the length and width. Find the volume.
The formula for finding the volume of a rectangular parallelepiped:
V = a * b * c, a – length, b – width, c – parallelepiped height.
1) Let us express the length of the parallelepiped in dm:
20 cm = 2 in.
2) Find the width of the parallelepiped:
2 + 1 = 3 (dm) – the width of the parallelepiped.
3) Find the height of the parallelepiped:
2 + 3 = 5 (dm) – the height of the parallelepiped.
4) Find the volume of the parallelepiped:
2 * 3 * 5 = 30 (dm ^ 3) – the volume of the parallelepiped.
Answer: the volume of a parallelepiped is 30 dm ^ 3.
